Hi there.
I too have had bouts of it this year. I think mine was more derealization. We have a new member Manicmarj who's been talking about
it too recently and many other posts about
it.
You are definitely not alone! You described it perfectly. My bouts would last for a day or 2. I describe it as "feeling like a stranger in your own familiar world."
I've been told it's occurs when we are mentally exhausted from anxiety/stress. I think more people have had it but dnot know how to explain or describe it bc it's just so darn weird! At least a panic attack is familiar (albeit rotten), but the DP/DR is just gross. It hovers over you like a dark cloud.
Mine has gotten better with time & getting my anxiety & depression under control with antidepressants and therapy.
You are DEFINITELY not alone with this one. Nor are you crazy or going to go crazy
Hang in there & sending you much peace!
